As the performance of railway infrastructure increasingly depends on the quality of geospatial data, network operators face a dual challenge: obtaining high-precision LiDAR surveys while minimising operational disruption and trackside interventions.
Reliable, fast and track-free LiDAR surveys
Traditionally, LiDAR survey campaigns in the railway sector involve installing sensors directly on tracks or trains. While accurate, these methods are often invasive, costly and logistically complex, with significant safety constraints.
Infrastructure managers are now seeking solutions that reduce operational impact while delivering sufficiently high-resolution data to feed advanced analysis and modelling software.
A non-invasive technology for high-resolution surveys
Helimap, a subsidiary of Sixense, has established itself as a key player in airborne LiDAR data acquisition and processing. Using helicopter-mounted technology, Helimap can perform non-invasive surveys with a resolution equivalent to ground-based methods.
This approach enables large areas to be covered rapidly without disrupting rail traffic, while ensuring data quality meets industry standards.
A collaboration with TopoDOT to go further
In line with its innovation strategy, Helimap has partnered with TopoDOT, a global leader in LiDAR data extraction software. This collaboration ensures seamless compatibility between Helimap’s datasets and the advanced tools used by infrastructure managers.
